Facebook has urged internet users not to meet strangers they have only had contact with online after a teenage girl was kidnapped and murdered by a man she met on a social networking site.
In a statement, Facebook said it was "deeply saddened" by Ashleigh's death. The statement urged people not to meet anyone they have only had contact with online unless they are certain they know who they are, "as there are unscrupulous people in the world with malevolent agendas".
The mother of the murdered child urged people to - "Please just be careful. Make sure you please do tell somebody if you are going to meet a person. That is the message, don't go on your own."
